Application filed July 29, 1921. Serial No. 488,484.

To all whom it may concern:

Be it known that I, ANDREW C. 001), a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Motometers, of which the following is a description.

My invention relates to improvements in motometers and more particularly to a motometer which may be illuminated so that the thermometer may be observed and read in the dark as well as in the light. Among the other objects of my invention I have sought to provide a device of the kind described which is simple, convenient, com- 'pact, economical, attractive, durable, and

efiicient andsatisfactory for use wherever found applicable. Many-other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosure hereingiven.

To this end my invention consists in the novel construction, arrangement and combination of parts herein shown and. described, particularly pointed out in the claims.- j r In the drawings, wherein like reference characters indicate like or corresponding parts;

Figure 1 is an elevation of my invention as applied to a radiator cap, viewed'from the drivers seat;

Figure 2 is a side elevation thereof;

Figure 3 is an elevation similar to that shown in Figure 1, viewed from the front of the vehicle;

Figure 4 is a sectional'view taken substantially on the line 44 of Figure 1;

Figure 5 is a sectional view taken substantiallyon the line 55 of Figure 1 parts being broken away; I

Figure 6 is a view similarto thatshown in Figure 1 and represents a modified'form of the device; and

.being ofany desired 'shape and material and comprising a chambered casing having opposed front and rear walls, 3 and 4 respectively, said walls having central openings 5 therein preferably adapted to receive lenses, covers or glasses 6 and 6' therein.

Extending vertically in the chamber of the 1 motometer casing, substantially centrally -thereof, is a thermometerstem 7, and to one side thereof,'that is, to the front of the stem,

as shown in the drawings, is arranged a dial or partition 8, said dial being generally of an opaque material and having markings thereon (not shown) for indicating the temperature, proportional to the height of the indicating fluid in the thermometer stem. A c rcle 9 may be imprinted on the face of the dial, as shown'in Figure 1, at any desired portion thereof relative to a certain predetermined temperature point recorded by the thermometer stem, or hole provided.

One or more lamp housings 10, as shown, 7

forward of the motor vehicle, said housing .being of any desired shape. The rear end "of said housing is threaded so as to receive a closure plug 12, said closure plug having a lamp socket 13 inwardly thereof and having .a terminal contact 14 adapted to engage the cooperating base contact of the lamp 15. there being a lead wire 16 connected to said socket. The lead wire 16 is preferably arranged within the casing 2 and extends therefrom at the base so that it may be detachably connected as at 17 to any suitable source of electrical energy, such as a storage battery, generator, or the like.

The housing 10 is so formed that it has an 7 opening 18 therethrough in the wall thereof communicating with the interior of the easing 2, as shown in Figure 4, so that a portion of the light from said lamp 15 will be directed downwardly between the opaque partition ,8. and the thermometer stem 7 in order to illuminate said stem so that it can be read from the drivers seat at night as well as in the day time. One of thecovers, as for instance 6, may be opaque and of sheet metal stamping, or it may be of a transparent or translucent material and have any-suitable or preferred emblem or design 19 thereon, it being illuminated from behind, as shown in Figure 4, when the lamp is lightd.-' If desired; a partition 8" of any suitable material having a photograph, emblem or design thereon may be arranged, as shown, or a transparent design sheet mounted immediately behind the lens 6'.

In the modifications shown in Figures 6 and 7 the transverse lamp housing 10 is dispensed with and a pair of lamps 21 are arranged in the casing 2 on opposite sides of the thermometer stem 7. In this modification'the opaque dial or partition 8 extends from one side to the other of the casing, adjacent the rear side thereof against the glass or cover 6, said partition forming a boxlike or looped structure about the stem 7 open at only one side thereof, as at 22. In the opposite walls of the partition 8 are formed one or more, apertures 23 in registry with the thermometer stem so that light from the lamps 21 may pass through said apertures and onto said stem, whereby said thermometer may be read from the drivers seat. It will be observed in this modification that the cover plate 6 is illuminated directly by the lamps 21.

I What I claim as new and desire to secure by Letters Patent is:

1. In a device of the kind described and in combination, a. motometer comprising a casing having a thermometer stem therein, a vertical partition substantially enclosing said stem and extending to one side thereof, said stem enclosing portionof the partition having an aperture therethrough,said casing having openings in the opposite faces thereof to receive covers therein, a housing at the upper end of said casing having an opening communicating with the interior of said casing, said housing being open at its ends, a lens arranged in one of theopen ends of said housing, detachable closure means for the other ends of said housing, and a lamp removably positioned within said housing whereby said lamp may be illuminated so that the light therefrom is directed through said communicating openings into said casing compartments so as to illuminate said stem.

2. In a device of the kind described and in combination, a casing having openings at the sides thereof, covers for said openings, partitions in said casing vertically lamp to illuminate said compartments.

3. In a device of the kind described and in combination, a motometer comprisinga casing having a thermometer stem therein, a vertical partition in said casing and, sub

stan-tially enclosing said stem and having an aperture therethrough opening onto said stem, a housing at the upper end of said casing having an opening communicating with the interior of the casing, and a lamp within said housing, whereby light therefrom will illuminate said stem.

4. In a device of the kind described and in combination, a motometer comprising a casing having a thermometer stem arranged therein, a vertical partition substantially enclosing said stem and provided with an aperture through that portion adjacent the stem, a housing at the upper end of said casing and having an opening communicating with the interior of the casing, said housing open at its ends, a lens arranged in one of the open ends of said housing, detachable closure means for the other end of said housing, and a lamp within said housing, whereby the light therefrom will be directed through said communicating openings to illuminate said stem.
